Wood – From solid wood to solid surface materials

sia Abrasives covers the entire range of products for the surface treatment of solid wood, wood-based materials, solid surface materials, paints and lacquers in furniture and interior work, kitchen and shop fitting, restoration and renovation, as well as in the painting trade.

With a variety of abrasive forms – ranging from discs, wide and cross belts to sanding blocks in different shapes and hardness – we try to meet all user requirements for surface quality, lifetime and mechanical load and, in most cases, even exceed them.



For any application

Calibrating, sanding down, removal, keying, intermediate sanding, fine sanding, final sanding, preparation for polishing, coarse sanding and profile sanding



For all wood types

For hardwood, wood containing oil or resin, and softwood as well as solid wood and veneer

The differences: Because of its fibrous nature and close vascular structure, hardwood is a strong, heavy wood. Its slow rate of growth makes the wood dense and hard and thus difficult to finish. Hardwoods include beech, oak, walnut, maple, limba, American cherry, wenge, sipo, ramin and birch.

Both hardwoods and softwoods can contain resins or oils. They store resins or oils in their cellular structure. These protect the tree from extreme weather conditions and help it to heal after sustaining physical damage. The oils and resins, however, adversely affect the wood’s sanding properties. This genus includes spruce, jelutong, larch, pine, Douglas fir, Weymouth pine, durian, Asian oak, iroko and teak.

Light wood is referred to as “softwood”. As softwood grows more quickly than hardwood, it has a comparatively loose, open and soft vascular structure. This is why softwood is easier to sand. Yew, hemlock, fir and redlock are often used for cabinetry, parquet floors and saunas.



For the most commonly used wood-based materials

For plywood. Especially for calibrating and sanding out scratches as well as for fine sanding prior to lacquering.

For particle boards. Especially for calibrating and sanding out scratches as well as for fine sanding prior to lacquering.

For MDF. For calibrating panels prior to application of paint, fine sanding before lacquering or profiled edges.

Also suitable for particle boards, HDF boards, OSB panels, blockboards, glued wood panels, switch panels, synthetic resin panels, laminates and mineral boards.



For classic and very hard solid surface materials

Working with polymer-bonded mineral materials (known as “solid surfaces”) is widespread in the carpentry trade and has become increasing popular especially in recent years. The variety of materials has also increased as a result of new suppliers, a broader range of colours and innovative new technical features. Thanks to the fact that they have a pore-free surface, are insensitive to moisture and are also food safe, polymers are mainly used in bathroom, kitchen, office, clinic and shop fittings, and they create the appearance of marble or granite. Depending on their workability (hardness), the condition they are delivered in and the customer’s requirements in terms of the finished product (surface gloss), these materials can however cause the worker major problems. We offer the perfect system for working classic solid surface materials such as Corian®, Varicor®, Kerrock®, Avonite®, Creanit®, Hi-Macs®, Staron® and Marlan® as well as very hard solid surface materials such as Askilan® or Silestone® – through to marble and granite.



For paints and lacquers

We offer abrasive systems for all common paint and lacquer applications – be it intermediate sanding or sanding out lacquer defects, manual sanding, portable machine sanding, profile belt sanding, cross/stroke belt sanding or wide belt sanding: UV-hardened lacquers, polyester lacquers (unsaturated polyesters), water-based lacquers, NC lacquers (nitrocellulose), PUR (polyurethane) lacquers as well as oils and waxes.
